Translation PHP Files (1 post)

I've inherited a website at work that was setup in the following manner:
Header, navigation, and bottom-footer are all tied directly to .php files on our FTP server. (ie. we aren't using Appearance>Menus for nav)

To have these files work with multiple languages, translated files are created. For example:
nav.php = nav_de.php for German, _es for Spanish, etc.
bottom-footer.php = bottom-footer-de.php etc.
